FAQ

Questions buyers ask

Do we need to use one vendor's agents?

No. InterAgents is vendor-neutral and focuses on the handoffs between agents.

Do you host our agents?

No. It designs and tests the connections; your agents run where they already run.

Is our workflow data kept private?

Yes. Logs and designs are used only for your project.
